Permanent Maps field first: keep the everyday website button focused on the service, city, proof, or quote page a first-time searcher actually needs.
Booking campaigns stay temporary: use booking links only for narrow appointment types, repeat demand, or short-lived campaigns that can survive without extra trust-building context.
Review and QR links stay separate: post-job review asks, leave-behinds, and QR cards can reuse the business profile, but they should not hijack the permanent website field.
Referral links stay source-labeled: if a partner, truck, or invoice handoff needs one action, record that as a separate route instead of overwriting the default Maps destination.
